IMPROVEMENT lN VENTILATIG CARRIAGES.

Specitication forming part of Letters Patent No. 175,364, dated March 28, 1876; application tiled January 15, 1876.

To all whom if may conce-ra.-

Be it known that I, EZRA MARSH, of Newark, Essex county, New Jersey, have invented a new and useful Improvement in Ventilating Carriages, ot' which the following is a specification Figure 1 is a longitudinal section of a carriage to which my improvement has been applied, taken through the line a: :n ma: a: az, Fig. 2. Fig. 2 is a t'ront view of the same, partly in section. through the line y y, Fig. l; and Fig. 3 is adetail view through the line z z, Fig. 1.

Similar letters of reference indicate corresponding parts.

rlhe object of this invention is to improve the construction ot close carriages in such a way that fresh air, in any desired quantity, may be admitted, and the foul air allowed to escape, and, at the same time, without mar` ring 0r disfguring the carriage.

i The invention consists in a carriage-body, having its front top bar' and posts made holf low or tubular, and provided with the opening to admit fresh air to the carriage-body, and in a carriage-body provided with the space and the'openiugs or holes for the escape of foul air, as hereinafter fully described.

A reinesents'the body ot' a carriage, which is provided with a door Iand windows in the usual way, to enable it to be closed in cold and stormy weather. The front top bar B ot' the body A is made hollow or tubular, and has holes b in its outer side and directly beneath the drip-molding al ot' the roof. The front posts C of the body A are made hollow, and at the upper ends their cavities communicate with the cavities of the top bar B. In

the lower part of the inner sides ot' the posts C are formed openings c', through which the cold air is discharged into the interior of the carriage-body A. The openings c should be provided with'a register or slide, which is not shown 'in the drawing, to enable the admission of cold air to be controlled, as desired. In the back, sides, or top ot' the body A is formed a space, a2, by interposing a sheet or plate, D, of strawboard, `or other suitable material, between the upholstering and the Walls ot' said body, through which sheet or partitition D a hole, d', is formed, to allow the foul air from the carriage-body to pass into said space. Frein the space a2 the foul air escapes through holes a3 in the side or back of the carriage, beneath the drip-molding ad. The opening d should be provided with a slide or register to enable the ventilation to be-controlled, as desired. Ink case the space a2 should be crossed by timbers of the carriage-body frame, said timbers'should have holes formed in them to allow the foul air to pass freely to thetholes a3.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A carriage-body having its front top bar B and posts G made hollow or tubular, and provided with the openings b c to admit fresh air to said carriage-body, substantially as herein shown and described.

2. A carriage-body, provided with the space a2 and the openings or holes d a3 in its rear part for the escape ol" foul air, substantially as herein shown and described.
